FOUNDRY SLIPJACKET.

Specification of Letters Patent.

Applicationfilecbflctober 21,1918. Serial No. 259,078.

To all who-m itmay concern.-

Be it known that 1, WILLIAM Peon, a citizen of the United States,residing ill} the city and county of Kalamazoo, State of Michigan, haveinvented certain new and useful Improvements in Foundry Slip- Jackets,of which the following is a specification.

This invention relates to improvements in foundry slip jackets.

The main object of this invention is to provide an improved meta-lfoundry slip jacket which is very durable, strong and rigid, and at thesame time comparatively light and one which is economical tomanufacture.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

ll accomplish the objects of my invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisspecification, in which:

Figurellis a perspective view of one embodiment of my invention.

Fig. TI is a perspective view of another embodiment of my invention.

Fig. HT is. an enlarged detail horizontal section through one of thecorners on a line corresponding to line 3-3 of Fig. I.

Fig. TV is a detail section similar to that of Fig. TIT before the wallplates and fillet are united at the corners.

Fig. V is a vertical section on a line cor responding to line 5-5 ofFig. T.

In the drawings similar reference characters refer to similar partsthroughout the several views.

Referring to the drawing, the walls 1, 1 and 2, 2 of my improved slipjacket are plates of steel, preferably pressed steel. The corners of theplatesare brought totogether with fillets 3 in the angles thereof andare integrally united throughout by fusing welds inside and out, thewelds being acetylene or electric, both processes being used, whichprovide substantially unitary corners and thus, in effect, an integralstructure.

Tn the embodiment shown in Fig. 11 T iners, as at 5.

provide a surrounding reinforcing frame and handle member formed ofangle iron pieces a mitercd and fuse welded at the cor- These pieces 4:are disposed with their angles facing downwardly. This provides a rigidintegral rectangular frame which is slipped over the jacket. The jacketis preferably tapered and the frame is driven .down firmly on the outerside thereof and the vertical arms of the frame secured by rivets 6, therivets being countersunk within the jacket so as to leave its innerwallsperfectly smooth. The horizontal arms of this frame are curveddownwardly at their outer edges, as at 7, so that the embracing andreinforcing frame forms hand pieces.

In the embodiment shown in Fig. T short angle iron pieces 8 are rivetedto opposite walls of the jacket with their angles facing downwardly bythe hand pieces. The handles in this embodiment do not constitutereinforcing members. This jacket is welded at the corner by both theacetylene and electric welding process preferably the electric weldwhich provides a corner that is perfect, tight and through which no gascan escape which would cause rusting and corroslon.

The advantages of this jacket over a riveted angle at the corner arethat extreme accuracy is gained which is absolutely necessary for propermold protection; further that the corners will always remain the sameand cannot spread or pull apart.

My improved slip jacket is very strong and rigid, being capable of andwell adapted to withstand rough usage, such as rough handling in thefoundry or in transportation without being sprung or otherwisedistorted.

Having thus described my invention, what I claim as new and desire tosecure by Let ters Patent, is:

1. In a foundry slip jacket, the tapered side walls of which are platesof steel, there being metal fillets in the corners, said wall plates andfillets being united throughout at the corners of the jacket by fusingwelds inside and out providing an integral structure, and a frameembracing said jacket, said frame being formed of pieces of angle irondisposed with their angles facing down wardly and united at the cornersby fusing welds providing an integral structure, the vertical legs ofthe frame being riveted to the side walls,v the horizontal legs thereofbeing curved downwardly and constituting handles.

2. In a foundry slip jacket, the side walls of which are plates ofsteel, there being metal fillets in the corners, said wall plates andfillets being united throughout at the corners of the jacket by fusingWelds inside and out'providing an integral structure, and a frameembracing said jacket, said frame being formed of pieces of angle ironunited at the corners by fusing welds providing an integral structure,the vertical legs of the frame being rivetedto the side walls.

3. In a foundry slip acket, the side walls of which are plates of steel,said wall plates being united throughout at the corners of the jacket byfusing welds inside and out providing an integral structure, and a frameembracing said jacket, said frame being formed of pieces of angle ironunited at the corners by fusing welds providing an in 4. A foundry slipjacket, the tapered side walls of which are plates of steel, there beingmetal fillets in the corners, said wall plates and said fillets beingunited throughout at the corners of the flask by fusing welds inside andout providing an integral structure, and angle iron members secured tothe walls with their angles facing downwardly, the upper arms of saidangle iron members being curved downwardly providing handles.

In witness whereof, I have hereunto set my hand and seal in the presenceof two witnesses.
